I have come into ownership of a Rebote 2.5 Delay PCB from Tonepad.com (bought at a sort of a garage sale).

I don't have a lot of interest in using it with a guitar, but I would like to use it in my modular. I happen to already have the PT2399 delay chip for it, so it should be an easy build.

The question I have is what should I do about signal voltage levels?

I've read through Ken Stone's pages about going the other way, using his stomp box adapter to use modules as guitar pedals, but I only see a brief mention of using an attenuator for the output, but don't even see the attenuators in the circuit.

I'm not having any great luck finding anything about going pedal to modular anywhere else either.

I have built several of the CGS stomp box adapters to use in my logic synth. All I know is that without them I was hammering the inputs of the pedals with close to 12V and the pedals were not dealing with this at all. I breadboarded the CGS adapter and hey presto- it worked. It's a simple circuit. I made three of them on a piece of stripboard. Give it a try on breadboard and see what you think.

+1 For the Ken Stone circuit.
I did a layout and etched some boards for it, works fine. IIRC I did change the attenuator and gain to further reduce and amplify signals, because I still had pretty large signal swing going into the pedals when I built it stock.

Yes the Ken Stone adapter is a must have for anyone who's got pedals!
I also use it to feed my pedalboard with high levels signals (anything like line outputs from a mixer works fine too).
The schematinc is really simple so it's easy to build a custom version from scratch on perfboard too.
Really it changed my life
edit: try to send some drums in a Tech21 Sansamp with this circuit
